: I updated my BIOS to the latest from IBM and put a Intel PIII 1000 Mhz(Coppermine) CPU slot1 in the Computer. After that the BIOS said the the CPU was a 750 Mhz cpu. What can I do to get the computer to understand that it is a 1000 Mhz. I tested my computer with Intelīs test program and it said it is a 1000Mhz Cpu.: Remember that it is a IBM so I Can not change my multiplier and FSB speed, that stands at 100Mhz.

: : Is there any resone to update my chipset, Intel 440BX/ZX, 82443BX/ZX and would it be any god.?

NO WAY to change your chipset without changing the mainboard.

It appears that the fastest PIII CPU supported by the BIOS update is 750 MHz. MAYBE IBM can tell you how to support your 1 GHZ CPU but probably no way without IBM issuing another BIOS update (NOT likely). I've seen shareware programs that claim to tweak FSB (SoftFSB, I think) and/or multiplier; one or both MIGHT work for you since your CPU multiplier is limited to 10x but you're using only 7.5x now so a tweaker might get you closer to 10x (worth a try, anyway). Search the internet for overclocker sites and hardware tweak sites.

NO HARM running your CPU slower (underclocking is OK and the CPU will run cooler), just aggravating that you can't use the power you bought.
